Get it?

You don't understand math either. Dude had 500gigs. People warning him about scratched cd's with that garuanty bull. I just told the dude to find an extra harddrive used or new and make a raid. If either drive fails....no need to backup software, the user wouldn't know his stuff is archived.

Don't be mad at me If I outsmarted you. You maybe looking for a job one day boy

If he decides to sit around and burn DVDs all day fine. Don't burn your data at the max speed. hugh? did you think that one? Joe in the mailroom won't be able to read your distro list because he device read no faster than 8x.

Now, that is a very interesting concept that you have just introduced LinenOise.

Compatibility is a key issue.............. hell, I had to get my brother-in-law in Alabama trace some 1-4x CDs and send them to me, so they would work on an old burner............ the locally bought 4-8 media wouldn't work.

That is why I mentioned that with my project I had to mothball compatible hardware as well.

Compatibility isn't an issue. I'm archiving the data for the future, meaning I will never use archaic hardware to restore the data. Secondly, I probably won't backup all of the data, as yes, it will take a lot of time to burn it all. I specifically want to use a medium for keeping data that I can store properly in a closet and be fairly sure I'll be able to read in the somewhat distant future. Hard drives seem to be more volatile, and for data that I'm not changing over time, it is a valid option to go with optical media. I don't understand why you're so against this discussion.

I think that I understand your requirement, and would agree that optical media is currently your best option, given the data volume that you are describing.

So long as you buy good quality media and store it properly, you should be OK for well over 10 years. I only mentioned specialist archival material because I was not initially sure of what you had in mind. It is obviously overkill in this situation, and way too expensive.

The alternative would be to use another hard drive, but, if it is to be used as a backup, then it must be external. This would be either a USB drive in its own case or a removable drive in its own caddy.

Basically, hard drives are electro-mechanical, so you have three possible failure vectors:

1. The electronics.
2. The motor and R/W heads.
3. The platters.

With optical media you only have to worry about deterioration, which would typically be caused by oxidation and ultraviolet radiation.

On the other hand, it is generally much quicker to store to a hard drive or solid state than it is to burn optical media.

DO NOT use RAID for archiving or backup; it is intended for neither.

The purpose of RAID is to provide processing continuity in the event of drive failure. Data archives and backups should always be stored remotely.

Trust me, I have seen several catastrophic electronic events that killed multiple drives at the same time.

1. The dynamic provision of processing continuity and thereby, business continuity, in the event of hard drive failure.

Principles of secure data storage 101:

1. Backup your data regularly.
2. Check that your backups work.
3. Make more than one backup.
4. Store at least one copy in a remote location and have one copy onsite for rapid restores.
5. DO NOT store backups on the same hardware as the data that are being backed up (other than if the copy is purely for rapid recovery)

RAID1 is patently unsuitable for backups or archiving. Sure, it stores a copy of the data which it dynamically updates in realtime, but that is purely coincidental to its real purpose of allowing processing continuity.

Just think about it folks: why take the performance hit of RAID1 when your data backup requirement is for static data? RAID1 will affect everything you do.

Also, just consider what happens at your corporation, business, institution or whatever. You make backups and store them securely, and offline (I sincerely hope!).

"Archiving" is a total no brainer if you understand the meaning of the word in the English language. It refers to data that you no longer require instant access to, and should be stored offline in a less costly fashion?

I have seen far too many RAID1 and non-RAID twin HDD devices where both drives have been creamed by the same event, to think otherwise.

So, are all the professionally run outfits wrong and LinenOise right?.......... I don't think so

@LinenOise:

Other dude recommended a usb external drive for backup. However dude is against Raid devices. That's something McCain would say! why he lost.

To avoid looking even more foolish I would strongly recommend that you read other people's posts more carefully before reacting (I cannot credit your post with the merit of a "response")

What I said was:

The alternative would be to use another hard drive, but, if it is to be used as a backup, then it must be external. This would be either a USB drive in its own case or a removable drive in its own caddy.

I even emphasised the external factor for ease of comprehension.........apparently I failed At no point did I "recommend" anything; I merely suggested alternative strategies.
